Specification of Letters Patent. Patented A g. 15 1922 Application filed February 1, 1918. Serial No. 214,853.

To all whom it may concern:

Be it known that I, GEORGE S. TIFFANY, a citizen of the United States, residing at Summit, county of Union, and State of New Jersey, have invented certain new and useful Improvements in Telautographic Apparatus, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to improvements in telautographic apparatus.

It is the object of the present invention to provide electro-mechanical telautographic apparatus, designed for use in bulletin board and like announcements, in which the lateral movements of the receiving pen are controlled by the transmitting tracer through mechanlcal connections from the transmitter to the receiver, and in which the movements of the receiving pen to and from its writing surface are controlled by the transmitting tracer through electricalconnections from the transmitter to the receiver.

Another feature of the invention resides in the combination with the telautographic apparatus of projecting mechanism for magnifying the writing done by the receiving pen and projecting or throwing the same upon a screen, bulletin board or the like.

In the accompanying drawings Figure l is a side elevation of a combined telautograph and projecting machine embodying the present improvements;

Figure 2 is a plan view of the same;

Figure 3 is an end view of the same, partly in section;

Figure 4 is a vertical section on the line 4 of Fig. 3;

Figure 5 is a plan view, partly in section, of the transmitter;

Figure 6 is a vertical section of the same;

Fi ure 7 is a diagrammatic view of the circuits controlling the electric light apparatus of the projecting machine and the raising and lowering of the receiving pen.

Figures 8 and 9 illustrate a modification hereinafter described.

Referring to said drawings1 represents the base of the machine on which is mounted the transmitting instrument, and 2, 3 a pair of standards rising therefrom on which is mounted the receiving instrument and a pair of horizontal rods 4; 5, on which is adjustably mounted the projecting mecha- IllSIIl.

The transmitter comprises a pair of levers 6, 7, secured, at their outer ends, to collars 8, 9-, loose on a pair of vertical oscillating shafts 10, 11, supported at their lower ends in plates 12, 13 on base 1 (in which standards 2, 3 are also supported) and journaled at thelr upper ends, in tubular brackets 14, 15, projecting, from frame 16 of the receivmg lnstrument. These shafts 10, 11 have fixed to their upper ends bevel gears 17, 18, respectively, forming, with said shafts, part of the connections between the transmitter and receiver, as hereinafter described.

Levers 6, 7 have pivotally connected with then inner ends a pair of tracer arms 20, 21, 1n the converging ends of which is pivotally mounted a tracer 22. Beneath tracer 22 a writing platen 23 is provided and in advance of the latter, that is, towards the front of the machine, there is provided an arm rest 24. Writing platen 23 is pivotally mounted, by means of arms 25 connected with it and extending under arm rest 24, and a rod 26 connected with said arms, in brackets 27 extending upwardly from base 1 5). Platen 23 is mounted so that in a wrlting operation, it will, under pressure of tracer 22, close a circuit, hereinafter described, from the transmitter to the receiver. Shafts 10, 11, also have secured to them rock arms 30, 31. The rock arm 30 is loosely con-' nected at one end by a link 32, with the rock arm 31, and at its diametrically opposite end by a link 33 with an arm 34 rojecting from tracer lever 7. Levers 6, are also loosely connected together by a two-part telescopic rod 35. The reason for this crossconnection between pen levers 6, 7, is that the position of the receiving pen arms 36, 37, is the reverse of that of tracer arms 20, 21, so that the movements of pen arm 36 are necessarily controlled by tracer arm 21 and those of pen arm 37 by tracer arm 20.

It will be observed that, as the tracer 22 is moved laterally, as in ordinary writing movements, pen-arms 20, 21 and levers 6, 7

will be correspondingly moved and shafts 30, 31 oscillated in one direction or another to a greater or less extent, according to the direction and extent of movement of tracer 22.

The receiver comprises a receiving of pen-arms 36, 37 pivotally secured to the inner ends of a pair of levers 38, 39, the op-.

posite ends of which have fixed to" them, shafts 40, 41 journaled in the tubular brackets 14, 15, before referred to, in re- I ceiver frame 16.. These shafts are provided with bevel gears 42, 43, meshing wlth bevel gears 17, 18, fixed to the upper ends of' shafts 10, 11. It will thus appear that as the shafts 10, 11 are oscillated, as just described, by the' writing movements pf tracer 22, shafts 40,41, will be correspondingly oscillated and through levers 38, 39,

and arms 36, '37, move receiving pen 28' in accordance with the movements of tracer 22,

and so as to reproduce the writing performed. by the transmitting tracer 22. p

A recording or writing surface 45 is pro= vided for receiving en 28, consisting of a sheet of glass, cellulo1d or other trans arent or sufficiently translucent-material, set in a receiver, with its point opposite bottle opening 51. The other movement (of the pen point into the opening) is accomplished suitable framework 46 therefor in frame 16. v

A source of ink-supply is also provided for receiving gen 28 consisting'of, a bottle 47 of ink carrie by a support 48 det'achably connected, by a stud and slot 49., 50, with frame 16. Bottle 47 is 'rovided with a side opening 51 through which receiving pen 28may be supplied with ink by the movement of the nections already described, between" the transmitter and receiver, by so arranging the bottle 47 that the position of its opening will correspond with the unison position of tracer 22. As the latter is moved to such position, the receiving pen 28 will, through such connections, be correspondingly moved and assume a like or. unison position in the from the transmitter through, other connections, which also raise and lower the receiving pen ,or move it from and to its recording surface 45, to begin a new line, make a correction, dot an i, cross a t &c. These other connections will presently be described.

The receiver is supplied with transparent or suficiently translucent film, preferably.

cellulose nitrate or cellulose acetate, from a supply 55 carrying a web 56 of such material and loosely mounted on a rod 57 fixed at one end to a tubular bracket 58 extending up wardly from frame 16. This bracket is pre- P P 28 mounted in the converging ends of apalr vided with a disk 59 for receiving and closing the inner end of a cylinder 60 adapted tobe slipped'over rod 57 and the web of film thereon, so'asto rotect' this latter from injury by weather, irt, &c. A thumb nut 61 onthe outer end of rod 57 holds cylinder 60 in position thereon. Cylinder 60 is provided with a. longitudinal slit 62 for the passage therefrom of the film strip,-which passes thence downwardly over writing surface 45 and between it and receiving pen 28, to a take-up spool 65. The latter is provided with a lon itudinal slit 66 for receiving the leading en of the film strip, so that as spool 65 is turned, it will draw the film strip downwardly over writing surface andpresent fresh writin portions thereof to receivingen 28, as t ey are required. Take-up spoo 65 is fast to a rod 66 journaled at its opposite end in brackets 67, 68,:depending from frame 16 and at one end this r0 is ropawl 70 torotate it and rod 66 and spool 65 step by step in one direction and by a detent 71 to prevent movement of these parts in the opposite direction. The operation of pawl '70 to so. rotate'rod 66 and spool 65 and thus feed the film strip downwardly over writing surface45 is effected from the transmitter through connections comprising a rock-shaft 72 journaled in a bracket 73 secured to standard 3, having a handle 74 at its outer end, and connected at its inner end with the lower end of a rod 75, the upper end of which is provided with the pawl 70. On the depression of handle 74, rod 75 is depressed and ratchet 69, rod 66 and spool 65 are rotated one step, so as to feed the film strip one line space over recording surface 45. Rod 75 and pawl 70 are again moved upwardly for the next operation by a coiled spring 76, the ends of which are connected with rod 75 and rock shaft 72 so as to restore them to normal position.

The connections from the transmitter to the receiver for eflecting the movementsv of the receiving pen 28 to and from its writing surface 45, are mainlyelectrical. They include, at the receiver a pen-lifting magnet 80, a rocking armature 81 therefor, and a pen supporting rod 82 connected with said armature and supporting the receiving pen. In the deenergized condition of magnet 80, armature 81 and rod 82 are retracted and receiving pen-28, therefore, rests against the film' strip 56 between it and its writing surface 45. The energization and deenergization of magnet is controlled by transmitter platen 23, as hereinafter described.

The receiver has associated with it a projecting machine comprising a casing 85 containingv electric light elements 86 and adjustably mounted on rods 4, 5, so that it may be moved to and from the writing field or surface 45 of the receiver. Casing 85 is also provided with a condenser-lens tube 87 strip by the receiving pen 28 will be magshown) nified and projected upon a screen (-not by the lighttransmitt'ed from are light 86.

The circuit for are light 86 consists of wire 90, to one carbon of said light, and wire 91, switch 92, wire 93, adjustable resistance 94, andwire 95 to the other carbon element; wires 90, 91 being connected with some convenient electric light service wires.

The. energization and deenergization of pen-lifting magnet 80, which,-. as before stated, is controlled by writing platen 23, consists of wires -96, 97 (the latter containing a resistance 98) contacts 99, 100., and

Wire 101 bridged across the light circuit just descrihed. Normally, contact 100, which is carried by a pivotally mounted yoke 102, is held in engagement with contact 99, by a spring 103, so that, when switch 92 is closed,

pen-lifting magnet 80 is energized and at-' tracts its armature 81, thereby moving pensupporting rod 82 outwardly and through the latter moving receiving pen 28 away from its writing surface 45 and film strip 56. This is also the position of receiving pen '28, during a writing operation, whenever transmitter tracer 22 is raised from its writing platen ,23. As shown, the platen 23 is arranged so as to engage yoke 102v and rock the same to disengage contact 100 from 'contact 99 whenever transmitter tracer dewill move pen-support-82," and with it receiving pen 28, away from writing surface --45.. Therefore,- while tracer 22 is in its lowered or raised position, receiving pen 28 will occupy a like position with relation to its writing field or surface 45. In each position it will follow the lateral movements of 5 I the transmitter tracer. Here it may be 1 noted that the unison position of tracer 22- is at the upper left hand corner of its writing field or platen 23 and that-the unison position of receiving pen is at the same polnt in its writing field, so that to. ink the latter,

all that the transmitter operator has to do is to move the transmitter tracer 22 to unison, and then lower it when the point of receiving pen 28, which has followedthe movements of the tracer, will be introduced into inkwell opening 51 and inked. I In the modified apparatus illustrated in Figs. 8 and 9, the pen-slgpporting rod 82 is omitted, the movement 0 the receiving pen 28 to and from its writin surface being effected by a spring 105, coi ed about a stud 106 fixed to frame 16 and. bearing against the outer side of pen lever 39, an an arm 107 mountedto move'endwise in frame 16 and connected with armature 81 of magnet and bearingagainst the-opposite side of pen lever 39. When magnet 80 is energized, arm 107, moving with its armature 81, will move receiving pen away from its writing surface and when said magnet is deenergized, spring 105 will move said pen to its writing surface.

What is claimed is: v a

In a telautograph, .the combination with a transmitter and a receiver provided with a tracer and pen respectively, of a pair of suitably supported oscillating shafts provided with gears, gears meshing therewith and connected with the receiving pen, and connections between said shafts and the transmitter tracer whereby the receiving pen is caused to reproduce the writing movements GEORGE s.
